Description

FIELD OF THE INVENTION

The present disclosure is in the field of electrical power line stringing traveler devices and methods of use.

BACKGROUND OF THE DISCLOSURE

Electrical demand in the United States and worldwide has grown exponentially along with the increases in population. To meet the electrical needs of the population increase, the utilities constantly upgrade systems in the power grid to add new power lines and/or to replace existing power lines with new power lines which may be able to carry more current. Power line stringing devices and methods are used between utility towers or electrical poles which may be separated by a varying distance.

During the power line stringing operation, a device called a traveler is used to string the power line. The insulator affixed to a pin on a utility tower or pole is removed and a traveler is affixed to the same pin. Then, the stringing of the power line is accomplished via the pin mounted traveler. After the stringing of the power line is complete the traveler is removed from the pin and replaced with the insulator. Alternatively, during the power line stringing operation, a insulator bracket is affixed to the insulator and a stringing block is affixed to the insulator bracket. Then, the stringing of the power line is accomplished via the stringing block affixed to the insulator bracket. After the stringing of the power line is complete the stringing block is removed from the insulator bracket and the insulator bracket is subsequently removed from the insulator. These two operations are widely used but are cumbersome due to the weight of the aluminum travelers and brackets and the amount of equipment required. Moreover, the number of steps of removing insulators and/or installing brackets and subsequently installing a stringing block.

Therefore, there is need for a lightweight stringing traveler device capable of being mounted directly to an insulator and a stringing method with the same traveler device that is more efficient and safer than current practices.

SUMMARY OF THE INVENTION

A method of stringing power lines with one or more travelers comprising the steps of: a) providing a plurality of insulators of electrical poles of a distribution or transmission line, each of which comprises a portion which includes an insulator clamping surface; b) providing a plurality of travelers for electrical power lines, comprising: i. a body portion comprising rubber, plastic or a combination thereof; and ii. an insulator clamping portion; c) removing the power line from each insulator; d) mounting each traveler to each of a plurality of insulators on a series of electrical poles of a distribution or transmission line; e) inserting a power line into each traveler, whereby the power line rests on the slideable saddle surface portion and is secured via the latch portion; f) pulling a power line along the slideable saddle surface portion of the plurality of travelers; g) tensioning the power line from each traveler to bring to provide a desired amount of sag between the electrical poles; h) removing the power line from the plurality of travelers; i) removing the plurality of travelers from the plurality of insulators on the series of electrical poles of the distribution or transmission line; j) removing the power line from the plurality of travelers; and k) remounting the power line on the insulator.
